Oregon State Police (OSP) is continuing the investigation into Sunday afternoon's single vehicle fatal traffic crash that occurred along Highway 34 east of Sheridan near SW Caleb Payne Road.

On March 9, 2014 at approximately 1:45 p.m., a 2013 Audi A4 passenger car driven by CATHIE SULLIVAN, age 67, from Portland, was eastbound on Highway 18 near milepost 36. As the car was negotiating through a left curve, it traveled off the right shoulder and into a ditch where it went airborne. The car struck a power pole and as it came to rest off the highway, both occupants were trapped inside.

CATHIE SULLIVAN was extricated by Sheridan Fire District firefighters. She was transported by air ambulance to Legacy Emanuel Medical Center with serious injuries.

Passenger RICHARD SULLIVAN, age 92, from Portland, was pronounced deceased at the scene.

PGE personnel came to the scene to repair the damaged pole.

OSP troopers from the McMinnville Area Command office are continuing the investigation into the cause of the crash. Speed is not believed to be a contributing factor. Trooper Nic Cederberg is the lead investigator.

OSP was also assisted at the scene by Yamhill County Sheriff's Office and ODOT.
